Westfield, Massachusetts, October 23, 2025 – Tighe & Bond, a Northeast leader in engineering, design, planning, and environmental consulting, is pleased to announce it has acquired Geosphere Environmental Management, Inc., a New Hampshire-based hydrogeology and environmental firm.
As a trusted groundwater advisor with service offerings in hydrogeology, geothermal, and environmental science, Geosphere’s client base includes public municipal and utility, as well as private sector clients.
